wtf? You forgot MGS4, which si pretty much Sony's own "Halo 3", their flagship. And then we still have God ofWar 3, which was just recently released. Gears of War 1 and 2 are out how long now?
I think the most important reason is still the huge 360 fanbase in NA, where the majority of games are sold.

playing right now: Xenoblade Chronicles
Hype-o-meter, from least to most hyped: the Last Story, Twisted Metal, Mass Effect 3, Final Fantasy XIII-2, Final Fantasy Versus XIII, Playstation ViTA
bet with Mordred11 that Rage will look better on Xbox 360.
